Figure '7 is a schematic electrical diagram of the circuits of the phonograph immediately as- 10 sociated with my invention.

The phonograph in which my invention has been embodied may be generally described with reference first to Figures 1, 2 and 3. It includes a cast base plate l having a forward portion l" l5 which is generally horizontal but which curves upwardly at its rear la to join a raised horizontal rearward portion I', as best seen in Figure 2. This base plate may be provided with the downward flange lb around its periphery (as 20 seen in Figure 2), and along its rear edge may be hinged to a lower enclosure 2, the front of the base plate normally resting on a bracket 2a extending inwardly from the front of that enclosure. Extending upwardly from the base plate 25 I are the lefthand and righthand standards 5 and 5, respectively, and the intermediate standard l, these standards serving to support various elements of the phonograph as hereinafter appears. 30

Journalled in a suitable bearing in the standard 'l is a mandrel shaft 9 on which, to the right of that standard, is carried a record support in the form of a generally cylindrical mandrel I0. This mandrel, best seen in Figure 3, may for ex- 3, ample be in general of the form illustrated and described in. U. S. Patent No. 2,010,717, issued August 6, 1935, on application of H. F. M. Gramann. For present purposes it may be briey described as follows:

Within the standard 'l is disposed the lefthand end portion 301 of a stationary sleeve 304, the sleeve being provided with a flange 303 securing it to the right-hand side of the standard 1, and extending rightwardly to near the right-hand 4f end of the mandrel. The shaft 9 extends through the sleeve 304, the sleeve portion 301 forming a left-hand bearing for that shaft, and means (as in the mentioned patent) being provided at the right-hand end of the sleeve to form a right- 50 hand bearing for the shaft Within the sleeve. Outside the sleeve, and extending rightwardly from the 4standard l, there is provided a hollow shaft 309 whose end portions bear on the sleeve;

and at their right-hand extremities the inner 55 for engagementl with the smaller end of the bore 'outershafts' and 339 are appropriately secured together'ior joint rotation, a portion of the securing means appearing as the nut 3W.

Around the outerjsh'aft 309 throughout most of its length there issupported, as by discs 32| and 322, a hollow, substantially cylindrical 'but vslightly tapered shell 32|! which serves as a guide for th mounting ofl a cylindrical record on theA ymandrel. At the right-hand, smaller end of shell 32|) is a hollow conical chuck 327 having a'plurality of sections or jaws 32B. lThe smallere'nd of the chuck, or left-hand ends of the sections,are loosely connected to a supporting collar 33| se'- cured on the outer shaft 333 within theshell 320: l the larger end portion of the chuck extends outwardly ofthe shell, and isl shouldered so as to provide an enlarged conical bearing portion 333 of a recordmounted on the mandrel.- The outer ends of the chuck sections 328 are provided with inwardlyextending anges which, byr a coiled .spring 33llencircling the chuck sections 32B, are

held in abutment against the rig'htwardly convergent conical surface of a'knob 335.. A leftward ori inward extension 33.6 of this knob is slidably mounted onthe outer shaft 339, its movement longitudinal of the shaft being limited as by a,

screw340 passing through a slot 339 in the knob extension; and the knob is biased to rightward vmovement, to expand the chuck321, -by a spring 34| disposed within the knob and compressed between its inner end surface and the nut-3m.

To the left of the shell 320 there is slidably mounted on the outer shaft 309 a. record supporting and ejecting disc'v or head 352, formed with an outwardly extending' iiange 353 and a rightwardly extending, tapered 'annular ange 354 adapted to engage the larger end of the bore of a record mounted'on the mandrel. v'I'hehead 352 is also provided 4with a long integral sleeve 355 extending rightwardly about the shaft 309 to within the shell 320, and carrying an outwardly extending iiange 35,6 at its right-hand end;v right.-

ward movement of the head 352 is limited'by .the

impingement of the ange 356 against'the shell-` supporting disc 32| above mentionedpreferably through theintermediary of a washer 32| of felt or other shock-absorbing material. Secured j in and extending leftwardly fromvthedisc 32| and freely through the flange 356 are a plurality 'of rods headed at theirleft-hand lextremitiea'cneof these rods appearing as 33|; andfbeirw'een the head of each rod and the flange 356 there isl compressed a respective spring such as 359, the Y springs serving to bias the head 352 rightwardly.

At the left-hand extremity ci' the knob extension 336 there is provided an outwardly extending lip 338; and to engage this lip there isprovided a pawl 343, pivotally mounted on a pin 344 car-k1 f rled by a leftward extension 345 of collar 33|',A

and freely extending through thefchuck 321fto bring its extremityadjacent the lip. The-pawl is i biased clockwise (when viewed-in the `direction flange.

When va record R is mounted on the mandrel,

aeiaeva as indicated bythe dashedot lines in Figure 3, the record holds the head 352 in a leftwardly displaced position i'rom thatto which it is biased;

' ange'356, likewiseldisplaceixholds pawl343 out4 of engagement with lip 333;" and rknob 335 is sub- .jectedto its rightwardbias, so that the chuck 321 is expanded to internally grip the rlghtfhand end of vthe record*` and; through `the record, to. maintain head 352km the displaced position.

- rightwardly and thuseiect righ'tward, or eject-- ing, movement of the record. At the same time the rod 347 will be .permitted to move rightwardly in obedience to its bias, moving the pawl 343 into lip-engaging position and', assuming sumcient knob movement, actually causing engagement of the lip 333; this lip engagement will hold the knob 335 leftwardly displaced, and thus fthe ,chuck members contracted, until another record is mounted on the mandrel. The leftward movement of head 352 by a record in the nal portion of its movement onto'the mandrel serves .to disengage the pawl 343 from the lip 333,-whereupon knob 335 is permitted to obey its bias'and expand the chuck to establish the conditions illustrated and assumed atthe beginning o f this paragraph. 'v While the constructionv andioperation 'fof the mandrel has been illustratedand described in considerable detail, reference mayif desired be had to the mentioned patent for yfurther details.

The mandrel shaft lljextends 'to therleit'of standard l'toward a drivingipulley-|`|rrotatably mounted at the right of standard 5, the pulley I1 being rotated as by a belt and motor not herein lnecessary to show.` Secured to the-pulley I1,- and splined on'the jend portion of the shaft 3, are the respective elements i3 and I3 oa clutch 20. The element Iaisprovlded withan annular groove i9', in which there is ypositioned ajpinf2| secured in thev upper extremity of a' clutch-oper- 'out o'f engagement with the element I8, and so to engage and disengage the clutch to cause and" stop rotation of the mandrelby the pulley Il.

Above vand behind the mandrel there extend,A between *they standards Y5 and 6, the respective., carriage rods 23 and 24, along which there is A slidable a carriage 40.. The carriage extends for-- wardly over the, mandrel, and carries in its for;-

ward portion a 'translating-device 30 arranged for -co-o'peration with a recordv R on the mandrel. The' carriage vmaybe driven rightwardly along ,.ating arm 22; the arm position is controlled by a.

therods 23 and 24 by a `feed screwi25', journalled and engageable by a feed.nut21 carried in the carriage. The feed screw 25 may be rotated, by

.a train of gears 26 Acoupling it rotationally with the mandrel shaftS, coincidentally with mandrel rotation.

Y It will be understood that the mandrel -I and, i j the carriage. 40 form afsystem. forfp'roducing translation-,effecting relative movement between between standards Sand 6 behind the rod 2l,

therecord R. and the translating device 30-e. g..

, y erse'a spiral path on vthe 'recordfor thetransla-` tion of .oscillatory energyl intoa recording- -on rvthe record or vice versa.4 And while the `described ltranslation-effecting movement isl the v movement -pappropriate to theV type ofl record and type Aof yphonographwhich I havechosen for illustrative purposes, I intend no unnecessary limitation of' the broader aspects of the invention to those types or to the particular nature of that movement. 4

While the translating device 30 may in recordation be actuated by, and may in reproduction produce, oscillatory energy of any of a wide variety of natures, I have shown it as provided with an upwardly extending neck 29, to which a soundconveying tube (not shown) may be attached for the conveyance of sound to and from' the translating device. The translating device which has been chosen for illustrative purposes is a sound box, ingeneral of the form shown and described in U. S. Patent No. 1,989,198, issued January 29, 1935, on application of Charles Heunlich, to which reference may be had for typical details; for present purposes it is suiiicient to note only a few of the components of the translating device. It may include two members movably mounted in its lower part, the upper of these members being designated as 3| and the lower as 32. When both members are free of upward restraint, a smooth ball 34 attached to member 32 contacts the record surface, without effect on the latter, and a recording stylus 35 carried by the upper member 3| also contacts the record surface; the translating device is then conditioned for recorda'tion on the record-e. g., for the engraving in the record surface of a groove of depth undulating in accordance with sound energy supplied to the device through the neck 29. When the upper member 3| only is held upwardly, both the ball 34 and the recording stylus 35 are held away from the record, and a reproducing stylus 36, suitably carried by the member 32, is brought into contact with the record surface; the translating device is then conditioned for reproduction from the record-e. g.. for the emission through the neck 29 of sound energy translated by the device from an undulating record groove being traversed by the reproducing stylus 36. When both members 3| and 32 are held upwardly, the ball 34 and both the styli 35 and 36 are held away from the record; the translating device is then in neutral condition.

The carriage 4U is provided with a horizontal sleeve 43 secured between the sides of the carriage and extending for a distance leftwardlv from the left-hand side, this sleeve slidably surrounding the rod 23 and forming a long bearing for the carriage on that rod. The means for variously positioning the members 3| and 32, and thus for selectively conditioning the translating device, comprises a member 6D rotatably surrounding this sleeve 43 within the carriage; a mechanism (for example such as is shown in my co-pending application abovementioned), including lugs such as 38 on member 32 and lifting fingers such as 46 co-operating therewith. but not necessary fully to detail herein, for rendering the positions of the members 3| and 32 responsive to the angular position of member 60 about the sleeve 43; and a plurality of means for controlling that angular position.

That one of those means which is available for manipulation by the hand of the operator of the phonograph may be mentioned as a control lever 39, pivoted on a horizontal stud 39' at the righthand side of the carriage, and extending forwardly from that stud. A stud 59 is extended rightwardly from a lower portion of the 'member B0, through an arcuate aperture 42 in the righthand side of the carriage; and a link 10 is pivotally secured to this stud, and extends forwardly therefrom to have its forward extremity pivotally secured to the bottom of a short arm 39" integral with and extending downwardly from the control lever 39.

For purposes hereinafter apparent there is provided, in addition to the manually operable lever 39, another lever to the position of which the angular position of the member 6|) is responsive, and vice versa. This other lever appears as 12, being secured to member 60 and therefrom extending upwardly through an aperture 1| in the top of the carriage.

As illustrated in Figures 1 and Z, the control lever 39 is in its downmost position, lever 12 is in its most forward position, and member 60 is in its most counter-clockwise position (as viewed in the direction of Figure 2); both members 3| and 32 are free of upward restraint, and the translating device is conditioned for recordatlon. When the control lever 39 is in its upmost position, lever 12 in its most rearward position, and member 60 in its most clockwise positionk (for example about 60 degrees displaced from its illustrated position) member 3| only is held upwardly and the translating device is conditioned for` reproduction. When the control lever 39 and lever 12 and member 60 are all in their intermediate positions, both members 3| and 32 are held upwardly and the translating device is in a neutral condition.

It is desirable that the feed nut 21 be disengaged from the feed screw 25 throughout a neutral condition, but engaged therewith during either translation condition (l e., for recordatlon or reproduction) of the translating device. Accordingly the feed nut may be mounted, above the feed screw, on an arm 68 which forms a part of an integral arm system pivoted within the carriage as at 44, the other portions of which arm system include the upwardly extending arm 41 and the forwardly extending arm 65. The arm system is biased clockwise (as viewed in the direction of Figure 2) for engagement of the feed nut with the feed screw, by a strongspring 66 tensioned between the top of arm 41' and a cross rod provided in the rear top portion of the carriage. The arm 65 extends underneath a roller 5E carried on a horizontal pin 59 secured to member and the top of arm 65 is provided with a high centrally indented portion When the translating device is in recordatlon condition the roller 56 is behind, and when the device is in reproduction condition the roller is in front of, the center of portion 65"; but as the member 69 is moved into its intermediate position for neutral translating device adjustment, the roller 56 is moved onto the high central portion 65", forcing a slight counterclockwise rotation of arms 6541-68 and so a disengagement of the feed nut--the indentation of 65" serving if desired as a detent for the neutral translating device adjustment.

It is common, in phonographs of the general type described, to employ with each record an individual index blank, for example in the form of a slip, which is inserted in appropriate position in the phonograph and upon or in which there may be made annotations indicating points of error and/or correction in the recordatlon, lengths of dictation sequences, and the like--the slip being removed with the record and employed in later transcription from that record for the guidance of lthe transcriber. In thegures there has been shown a holder 80 for such an index slip, disposed just above the front of the base plate may consist of a slightlyinclined nat plate having folded-over front and back anges l, and held to the front flange ib of the base plate by a long bracket 18. At the front corners of the base plate I, to the left and right of the holder 80, the base plate may beformed upwardly into the inclined surfaces 'l5 and i6 substantially aligned with the holder; an index slip S may be slid leftwardly over the surface 16 into -the holder 80, the left-hand portion of the surface 16 being desirably provided with an indentation l1 for the accommodation of the finger in the manipulation of the slip. While any means for relating points in the recording to points on the index slip maybe employed, I have illustrated asimple pointer 'i4 extending downwardly from the front of the carriage 40 rand then forwardly over the index slip; this pointer, travelling longitudinally of the slip in accordance with the travel of the translating device longitudinally of the record, may be employed as a guide for p encilmarks or the like on the slip.

In `my co-pending application abovementioned I disclosed the perfomance of variousfunctionse. g., carriage return to initial (left-hand) position, placement ofthe translating device in neutral condition, etcby the act of removal of an index blank from its holder, and the performance of other functions-e. g., placement of the translating device in a predetermined translating condition-by the act of index blank insertion into its holder. According to the instant invention I perform, by the act of index blank removal, another function-the ejection of the record from its support, or mandrel I0. In carrying out the instant invention I may retain any or all of the functions of the index blank manipulation abovementioned; as an example, and for the particular purpose of insuring the freedom of any portion of the translating device (e. g., the styli) from contact with the recordl at the time of record ejection, I have particularly illustrated herein the placement of the translating device in neutral condition by the blank removal. 'I'he means for performing this function may be rst described, it may, though non-'limitatively, be generally similar to that disclosed for this function in my co-pending application, and in that event is electrically controlled by aswitch in suitable association with the slip holder 80.

, This switch may be contained within a. housing 8|, for example molded of insulating material,44 seen in position in the phonograph in' Figure 1 and illustrated 'in vertical cross-section in Figure 4. The right-hand portion of this housing is disposed within an aperture 80a cut into they left-hand ena of the holder an, whne the left'- "hand portion of the housing may extend into a slot a cut into the inclined "surface 15- of the base plate 'I'he housing may comprise a generally rectangular box. of the vertical dimension of which about half is disposed above and half below the plane of the index slip S (the term -vertical being here employed to denote right- .angularity to the slightly inclined plane of the slip) j and in this plane the housing may be provided with aslot 84 leadingrleftwardlyA from the right-hand housing extremity for about half the "length of the housing-the slot 84 serving to admit the slip, and its left-hand extremity serving I to -denethe fully inserted position of the slip.

'I'he housing is desirably 89 of insulating material.

In the housing 8| is provided the closedly biased provided with a cover by the pole |46 when the 2,212,673 below and forward of the mandrel i The holder switch 35 comprising a pair oi leaf springs @e having left-hand terminal portions vheld in an insulating stack 35a, vand extending rightwardly therefrom respectively above and below the plane of the slip S. Near their right-'hand extremities the springs are bent to touch each other in the ,y

absence of the slip; but they are provided at their extremities with the divergent cam portions 8S'. A slip S, impinging on these cam portions during its insertion, forces the springs apart and passes therebetween, thereby (in view of the insulating nature of the slip material) eiectively openingA the switch B5 and holding itopen so long as the slip remains inserted.

'For/automatically placing the translating Vdel5 vice in neutral condition by the removal of the slip S, I connect, across the power supply for the tem simultaneously open-circuiting itself so that,v

among other things, wasteful continued current ow therein will be avoided.` The described electrical arrangement is Figure 7, wherein the terminals |2'| and |22 represent the mentioned power supply; the switch 85 appears in this :ligure in open condition, with the slip S between its springs 86. The electrical features of the solenoid system |40, shown in Figure 7, are best understood'following a mechan ical description of lthat system, for'which referencev may be had to Figures 1 and 2,

The system |40 comprises a coil |4| having illustrated .in the schematic a front-and-back extending axis; a, rectangular l frame |42 of magnetic material surrounding and l supporting the coil, mounted on a horizontal platform |43 which extends'rearwardly. from the relatively high central carriage portion above the relatively lower rear vcarriage portion, and apertured axially of the-coiha magnetic plunger |44 movable axially of the coil therewithin; and a switchassembly |45 secured behind the frame |42 and operated by the plunger |44, the casing |45a of the switch .assembly appearing in Figures 1 and 2. vThe forward end of the plunger is bifurcated, and to it is plvotally connected the rear extremity of a rodj12a; vto the forward extremity of this rod is adjustably secured a U-shaped member 12b, which is pivotally connected to the top of the lever 12 abovementioned. Thus the position of the plunger axially of the coil corresponds with the condition of the translating device, being forward for a recordation condition, intermediate for a neutral condition, and rearward for a. reproduction condition. The

, components are apportioned and adjusted so that the intermediate plunger position will be the one moved by -the jplunger, a 'pair ofV contacts |41a- I41b'connected together by the pole |46 when the plunger is in forward position, and

a pair of contacts HBG-|481 l plunger is' in rearward position. Contacts |410,` and |48aare connected together to form one electrical side, and contacts |41b and |48b are-connected together to form the other electrical side, ofthe switch and this is electrically placed in coil |4|.-

series with the VThus when the;llever 'l2 is' vertically connected togetherl assembly |45,`

disposed, the translating device in neutral condition, and the plunger |44 axially centralized within the coil |4i, the switch assembly |45 serves to maintain the coil open-circuited so that it cannot be energized. But if the translating device be in either recordation or reproduction condition, and the plunger |44 thus decentralized forwardly (as in Figure '7) or rearwardly with respect to the coil I 4I, that coil will not be open-circuited at the switch assembly |45; then if the switch 85 be closed by removal of Lthe index slip, the coil I 4| will be energized to move the plunger |44 into centralized position, placing the translating device in neutral condition and open-circuiting the coil. And so long as no slip is in the holder and the switch 85 therefore remains closed, any attempt to place the translating device into recordation or reproduction condition will, in view of its re-closing of the coil circuit at the switch assembly |45, be iol lowed by an immediate restoration to neutral condition. Of course upon re-insertion of a slip inl the holder 88, the switch 85 will be opened, rendering the solenoid system |40 ineifective and restoring the free adjustability of the translating device.

For automatically ejecting the record by the removal of the slip S, I connect another circuit across the power supply, or terminals I 2I-I22, as seen in Figure 7. This circuit serially comprises a switch assembly 2401 hereinafter de` scribed, and an electromagnet 218 which, when momentarily energized, imparts va momentary ieftward movement to the mandrel knob 335 above describedthis movement causing record ejection from the mandrel, and the latching of the knob in leftwardly displaced position to maintain the mandrel ready for the mounting of another record, both as described above. The electromagnet 218 and its operative connection with the mandrel knob, best seen in Figure 3, may be first described.

. The electromagnet may comprise a side-toside extending core 21|, a coil 212 surrounding the core, and a U-shaped frame 213 of magnetic material extending above and 'at the right of and below the coil, the righthand extremity of the core 21| being secured to the central portion of the U. The frame 213 may be secured to the bottom of a bracket 214 bridged across the bottom of an aperture Ic which is provided in the base plate I underneath the pulley I1. At the lefthand or open extremity of the U-shaped frame 213 there is provided an armature 216 of magnetic material, resiliently held normally in spaced relationship to the left-hand extremities of the frame and core by a suitably formed ,leaf spring 215 secured to the armature and to the bottom of the frame; it will of course be understood that upon energization of the coil 212 the armature 216 will be attracted rightwardly into at least substantial contact with the frame and core extremities. A pair of vertical ears 211 are folded leftwardly from the top portion of the armature 216, and between these ears is secured a horizontal pin 218. This pin passes rotatably through the lower end portion of a lever 280, an intermediate portion of which lever is pivoted on a horizontal pin 219 secured between two ears 5a extending leftwardly from the standard 5 below the axis of the mandrel; the lever extends upwardly at the left of standard 5 to have its top end portion opposite the axis of the mandrel and of pulley I1.

As seen in Figure 3, the pulley I1 is rotatably mounted on a shouldered cylinder |1a whose left-hand extremity is secured in the standard 5. This cylinder, which is in alignment with the mandrel shaft 9, is of course centrally hollow, and that shaft is likewise made hollow: and through both cylinder and shaft there freely extends a horizontal rod 28|, the rod serving to couple the knob 335 with the lever 288. At least one end of the rod must be rotationally free, and I prefer that both ends be rotationally free, of those respective elements which the rod couples. Thus the rod may pass through a hole 335c in the end of knob 335, this hole forming a rotary bearing for the right-hand rod extremity; the outer or right-hand portion oi' this hole may be enlarged into the recess 335|), and in this recess the rod may be provided with a head 283 which, when the rod is leftwardly pulled, bears on the shoulder 335c between the two hole portions. In its other end portion the rod 28| may pass through a hole 28|l'a in the upper end portion of the lever 288, this hole forming a rotary bearing for the left-hand rod extremity; and nuts 282 may be adjustably secured on the rod immediately to the left of the lever, preferably so that the rod is just free of longitudinal play when the mandrel I0 carries a record and knob 335 is therefore in its rightward position. It will be obvious that upon momentary energization of the electromagnet 210 and consequent momentary counterclockwise rocking of the lever 28|), the upper end portion of the lever will move leftwardly the nuts 282 and the rod 28| with its head 283, and will accordingly move leftwardly the knob 335. The distances of movement of the various parts are so apportioned that this knob movement will be suilicient not only to eject the record but also to cause the abovementioned iatching of the knob in leftwardly displaced position. After lever 288 is restored (by spring-215') to its normal or illustrated position at the conclusion of the momentary electromagnet energlzation, and until the knob is restored rightwardly by subsequent record mounting, the rod 28| will have longitudinal play; and to prevent its head 283 from then protruding beyond the surface of knob 335 a thin plug 284 may be threaded into the knob recess 3351), though of course for a distance insuicient to bind the head 283 against the shoulder 335c.

The switch assembly 248 serves to control the energization of the electromagnet 210. 'I'he assembly includes a control member 24| moved to respective positions by the removal and by the insertion of a slip from and into the holder 88; but a feature of the assembly is that it functions to close the electromagnet circuit only momentarily (i. e., for an automatically restricted, very short time interval), and only as an incident oi' slip removal (and not also of slip insertion). 'I'he restriction to momentary closure is desirable not only to obviate wasteful current flow, but also so that if a record be mounted on the mandrel before the insertion of its accompanying slip (as is preferred according to my co-pending application abovementloned, and as in any event may Vfrequently be done) that record may be properly seated on the mandrel and not subjected to immediate ejection. The restriction to closure only upon slip removal (and not also on insertion) is strongly preferred so that, among other things, a record mounted before accompanying slip insertion shall not be ejected upon that insertion. It may be noted that in the switch assembly i1- lustrated for the performance of the so-limited Y switching function I have embodied features disclosed and claimed in my co-pending application Serial No. 252,523 filed January 24, 1939, and entitled Electric switching.

'I'he .switch assembly 240, illustrated in detail in Figures 2, 5 and 6, may be housed in a rectangular casing 242 of insulating material disposed (as seen in Figure l) underneath the righthand rear portion of the holder 80 and extending downwardly therefrom through a suitable aperture 239 provided in the base plate The base plate may have an inclined i'lange 238 folded downwardly along the front edge of this aperture, and to this flange may be secured a flat member 243-the casing being secured behind this member by screws 244I passing through the member into the corners of the casing, the member 243 serving as a cover for the casing, and the top of the casing being at least substantially in contact with the bottom of the holder 8U. In the top of the casing, underneath the rear holder flange 19 and about centrally of the side-toside casing dimension, there may be provided a rectangular aperture 242a; and above this aperture there may be provided, in the holder 8D and its rear flange 19, corresponding apertures 80h and 19h respectively. The control member 24| for the switch assembly 24|) is a short arm, pivoted on a horizontal screw 245 extending forwardly from the rear of the casing a little underneath the right-hand extremity of the aperture 242a. The free extremity of this arm is biased (as hereinafter appears) upwardly so that in the absence of a slip S from the holder 90 the arm extremity extends diagonally upwardly through apertures 242a and 80h toward flange 19, and preferably into the ange aperture 19h; as a. slip S is inserted into the holder, however, the left- -hand slip extremity will cam the arm 24| downwardly to the position illustrated in Figure 5,

' wherein the arm extremity bears against the bot- Y tom of the slip. lIt will be-understood that the provision of the aperture 19h in the ange 19 and the extension ofthe armv 24| thereinto, though not indispensable, are desirable to permit a reasonably wide throw of the arm by slip manipulation.

.Integral with the arm"24'| there may be provided an. arm 246 extending diagonally leftwardly and downwardly, and to this arm may be secured an extension 241 of insulating material; the arm extension 241 is biased upwardly (and the arm 24| thus biased as abovementioned) by a spring 249 tensioned between a pin 241a carried by the arm extension and a p in 248 secured to the rear of the casing thereabove. At the free end of the arm extension 241 there is provided i 'an electrical contact member 25|; when no slip Y is in the holder 89 the bias of the arm extension brings this contact member into" contact with a spring 252 secured on and extending rightwardly from a lug 253 formed inwardly from the left- 'hand side of the casing-the member 25| and spring 252 forming afswitchf25|l which is closed 65v pivoted at an intermediate point on a horizontal screw 255 extending forwardly from the rear of the casing, and held in a plane in front of that of the extension 241 by a bushing 255a surrounding the screw. Stop pins 256 may extend forwardly from the rear of the casing above and below the arm 251, separated to allow a swing for the arm typically of the order of 25 or 30 degrees. 'Ihe arm 251 may extend almost to the right-hand end of the casing, and at its right-hand extremity carries an electrical contact member 258; and a stationary contact member 259 is secured to and extends forwardly from the rear of the casing in appropriate arrangement to be contacted by member 258 during the intermediate portion of the swing of arm 251 from one stop pin to the other.

The switches 250 ad 260 are placed electrically in series as by a flexible conductor 268 connecting members 25| and 258, the spring 252 and stationary contact member 259 forming the elec.- trical terminals of the switch assembly 248.y The arm 251 is toggled to the arm extension 241 by a spring 26| tensioned between pins 262 and 263 extending forwardly from 241 and 251 respectively, the spring 26| being weak enough to avoid interference with the above described function of spring 249; and when a slip S is in the holder and thev arm extension 241 is thus held downwardly, arm 251 will be held by spring 26| against the lower stop pin 256. The arrangement is such that when the slip, being withdrawn, clears the control arm 24| and the arm extension 241 thus moves upwardly in response to spring 249, member' 25| will rst touch spring 252 to close the switch 250; almost immediately thereafter, during the continued movement of the arm extension 241 up to pin 254, the line of force of spring 26| will be brought suiciently above the axis of screw 255 to throw the arm 251 upwardly against the upper stop pin 256, thus momentarily closing the switch 260 after the closing of the switch 258, and imparting a momentary energlzation to the electromagnet 210. Upon the downward movement of the arm 241 attendant on insertion of a slip in the holder, however, the arm extension 241 will be moved downwardly sufllciently to open the switch 250 before the line of force'of spring 26| is brought suiciently below the-axis of screw 255 to throw the arm 251 downwardly; thus the momentary closure of switch 260 upon slip insertion occurs after switch 250 is opened and is therefore (in view of the serial connection of the switches) ineiective to energize the elec the electromagnet 210 upon slip insertion may aS- suredly be of suflicient duration for the full left" ward movement of knob 335 above described, the' While I have disclosed my inventionin of a particular embodiment thereof, I d o not intend that its broader aspects be limited by the details of that embodiment, which obviously may be widely varied without departure from the spirit of the invention. 'I'he proper scope of the invention I undertake to express in the following Claims-in somenof the claims broadly, subject however to such proper limitations as the state of the art may impose.
